I have a function that removes duplicates from a list, and if removed, fills again those blanks with another entry of another list with all possible entries.

Right now, I have a function which does this work, but I don`t know why, at time to store that complete list without duplicates in another list when I call it, it appears as "none". But it works properly. This is the function:

I am programming a lambda function in .NET Core 3.1(C#) and I want to leave log of the actions being performed in my logic, when I deploy my lambda in the AWS Lambda service in cloudwatch it adds an extra line that is only displayed in the output (also affects my local but not my plain text file) what could I be misconfiguring?

To create the project use the template "AWS Lambda Project (.NET Core - C#)" from the AWS Toolkit For Visual Studio 2019.

I'm trying to check how many days are left for my application, one from the current time and the second one from a std::string that comes from a database, but every time I try to subtract the 2 dates using

I have this df:

So I was doing a slider to change text size. I checked the docs and to do a slider with knobs and 3 values I wrote:

I have two large CSV with data that I want to compare. I used pandas therefore I have two data frames to work with easier, but the program takes too long to finish and compare all the data.

I am comparing the data sent with the received, in order to get the latency time, for that I put a double loop and the program works fine. But I want to know if there is a faster way to do this, because for my heaviest files it takes days to finish the program.

I am working with large files, the first has 68001 rows and the second has 837190 rows. But the program takes too long. Thanks in advance.

Explanation of how my code works

I am doing some performance tests of the MQTT broker, for which I created the paho clients that send and receive messages, the data sent was stored in a csv to later calculate the latency. The csv of the Publishers (users who publish) contains the publisher's client ID, the account, the timestamp, and the topic to which it is subscribed.

While the subscribers (users who receive the message) contain the timestamp when the message is received, the message received, the count (counter for the number of messages), the publisher's client ID and the topic.

Now to calculate the latency, evaluate row by row with a loop that starts at 0. That's why I used a loop for df1 (dataframe of the publishers) and the first row of the df2 (dataframe of the message receivers).

With the conditional "if" I compare the client's ID, the count number, and the topics where the messages were sent from the first row of the dataframe df1, which corresponds to the first client to send a message and I compare it with the first row of the dataframe df2, to see if the client ID, count and topic match.

If it coincides, I proceed to subtract the times to calculate the Latency, locating myself in the column corresponding to the times, and then store them in another csv, which is almost the last line you can see.

If the conditional is not fulfilled, continue and goes to the next iteration of the loop corresponding to the df2. Therefore df1 will remain in the same position until the df2 loop has finished evaluating if there are matches in all the lines of its dataframe. I hope I have explained myself well.

I have recently started with a Python course, and we are required to plot a histogram, and then retrieve the generated bins. The code is as follows:

I would like to know how I could optimise this Bubble Sort algorithm that I made in a portion of MATLAB code, or replace it by some other more efficient method like QuickSort, TimSort or Merge Sort In this case, Bubble Sort was used due to the fact that when the elements in the array to be ordered are swapped, the positions of the elements in another vector called categoria must also be swapped Thank you

I have been working on this for a couple of weeks now and yet again I am facing file issues. This sheet of code first gets all the entries existing in a database, then, after obtaining a series of ids, launches the same query with an additional WHERE clause to search for specific entries belonging to customers.

Finally, compares both resulting arrays in search of any entry that exists in the db but has not been asigned to any customer to print them onto a csv file so the user launching the code can attend the issues preventing those entries from being linked to a customer.

I have been suffering some issues in the past regarding files and permissions, but this time no error appears, no message alerting me that I don't have the authority to open a file in the desired location or anything.

I tried inserting some var_dump() along the sheet to see if the process really got to the fopen() which it does. It simply skips it, no file is created and no data written.

I looked at the server logs but found nothing and I have errors and warnings enabled.

This would take all entries from the database.
